5.1.8 Higher accuracy operation using a motor with encoder (Vector control)
(Pr. 9, Pr. 71, Pr. 80, Pr. 81, Pr. 359, Pr. 369, Pr. 800)
Full-scale vector control can be performed fitting the FR-A7AP and using a motor with encoder.
Fast response/high accuracy speed control (zero speed control, servo lock), torque control, and
position control can be performed.

What is vector control?
Excellent control characteristics when compared to V/f control and other control techniques,
achieving the control characteristics equal to those of DC machines.
It is suitable for applications below.
– To minimize the speed fluctuation even at a severe load fluctuation
– To generate low speed torque
– To perform torque control or position control
– Servo-lock torque control which generates a torque at zero speed (i.e. status of motor
shaft = stopped)
